[0001] The utility model relates to the technical field of oil and gas storage and transportation, in particular to a breathing nozzle for an oil storage pot. Background Art

[0002] During storage and transportation, the oil and gas pressure inside the oil tank or oil pot will fluctuate due to factors such as changes in ambient temperature and changes in the amount of oil stored. In order to prevent the oil tank from being deformed or damaged due to excessive or insufficient internal pressure and to reduce the evaporation loss of oil products, a breathing nozzle needs to be installed to balance the pressure inside and outside the tank.

[0003] In the prior art, the breathing nozzle allows gas to enter and exit the tank or kettle under a certain pressure. The traditional breathing nozzle structure is prone to impurities and is inconvenient to maintain. In addition, when a mechanical failure occurs in the breathing nozzle, it is difficult to make appropriate adjustments to ensure that the pressure inside the tank or kettle remains constant.

[0004] The patent with application number 202321145054.8 discloses a storage tank explosion-proof safety valve, including a storage tank fire-blocking breathing valve body, a valve cover and a connecting flange and other structures. The bolt through hole and the limit hole cooperate with the limit bolt and the limit latch screw to facilitate the disassembly and maintenance of the storage tank explosion-proof safety valve. The disassembly and assembly process is more labor-saving and not easy to slip. The structure of the storage tank explosion-proof safety valve is more stable. However, in actual use, no filtering device is installed on the air inlet and outlet, and there is a problem of impurities entering the liquid in the tank body or the kettle body.
